08/05/2015, 8:39 PMThanks a bunch. I'll play around a bit. - e

08/05/2015, 8:39 PMFor the record my dream right now is to get Python 3 + MyPy going. - c
cuddly-accountant-94274
08/05/2015, 8:39 PMWith MyPy presumably running as part of tests - e

08/05/2015, 8:39 PMI have no clue what a MyPy is - c

08/05/2015, 8:40 PMI still contend that if you're actually hacking on a given codebase regularly - this does not save much if anything, but it does help casual contrib or sporadic contrib - c
cuddly-accountant-94274
08/05/2015, 8:41 PMOr just many people on the same code base in general. Having the ability to define an interface that's not too easy to mis-use by validating input types etc is very attractive to me. - c
cuddly-accountant-94274
08/05/2015, 8:42 PMAnd it makes having explicit interfaces meaningful, without every contributor manually considering it. - c
cuddly-accountant-94274
08/05/2015, 8:42 PMBut, on this we can agree to disagree simple smile - e
enough-analyst-54434
08/05/2015, 8:42 PMNo - I do agree its a good tool for many (casual/onboarding/flipping between codebases) contributors - e
enough-analyst-54434
08/05/2015, 8:42 PMIts good for scaling coders - e
enough-analyst-54434
08/05/2015, 8:43 PMPants will probably use it if / when we can ever switch to just 3 - c
cuddly-accountant-94274
08/05/2015, 8:45 PMOkay. - e
enough-analyst-54434
08/05/2015, 8:48 PMI'm colored by an experience at a small 4 person startup where we transitioned from java3 -> java5 and fully adopted generics. It was fun and let you write less docs and use un-tortured names, but our error rate did not change and our speed did not change in any appreciable way - e
enough-analyst-54434
08/05/2015, 8:48 PMbut there were 4 of us, and were were deep in the codebase - e
enough-analyst-54434
08/05/2015, 8:49 PMI probably extrapolate too much from that - c
cuddly-accountant-94274
08/05/2015, 8:55 PMThe documentative value of declared types on public interfaces alone is something I like. especially when diving into a code base I've never seen before (like pants ;)). - c
cuddly-accountant-94274
08/05/2015, 8:55 PMAnd making re-factorings much safer. - c
cuddly-accountant-94274
08/05/2015, 8:56 PMThe latter being a very big deal - c

08/05/2015, 9:32 PM@cuddly-accountant-94274 mypy/py3 is not the way to go there. you should read up on the type hinting spec: https://www.python.org/dev/peps/pep-0484/ - c
cool-thailand-74745
08/05/2015, 9:32 PMthis is backwards compatible with py2 - c
cuddly-accountant-94274
08/05/2015, 9:32 PMmypy has stated that their goal is conformance with pep-484 - c
cool-thailand-74745
08/05/2015, 9:32 PMright, mypy may be a reference implementation of pep484 - c
cuddly-accountant-94274
08/05/2015, 9:32 PMIs there a better implementation? - c
cool-thailand-74745
08/05/2015, 9:33 PMit may be the only implementation that is relevant to us (i imagine that IDEs will implement it too) - c
cool-thailand-74745
08/05/2015, 9:33 PMi think the windows guys have an implementation for virtualwhatever - c
